LOITERING MODE FOR RIDER PICKUPS WITH AUTONOMOUS VEHICLES

The technology involves pickups of riders by autonomous vehicles in a manner that ensures the rider is picked up within an estimated time of arrival (ETA). For instance, in accordance with customer authorization, the autonomous vehicle may loiter or otherwise stay within a certain proximity (e.g., distance or time) to guarantee rider pickup within a predetermined time. One vehicle may be assigned to a rider for a set timeframe or multiple vehicles may be allocated to a particular event. Either approach may be used to ensure rider pickup with minimal waiting. One benefit is to avoid user-initiated ride requests when the customer is ready to depart a location, because a vehicle will already be present and ready to take the rider to their desired destination. Loitering may include prepositioning a vehicle at a given place, or driving autonomously to be nearby as needed.
